SAFETY noox.

Application filed. June 26, 1925. Serial No. 39,779.

This invention relates'to an improvement in safety hooks especially designed for the purpose of positively holding and locking in the hook the rope, chain, eye or other object engaged therewith thereby preventmg in ury to persons and damage to propment of the rope, chain,,-eye or the like from the hook.

Another object resides in the provision of adevice of this character which is of simple and durable construction, reliable and effective in operation and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a perspective view showing one embodiment of the invention, the removable side plate being detached,

Figure 2 is a View thereof in side elevation,

Figure 3 is an end elevational View. and

Figure 4; is a detail perspective view of the safety latch prior to assembly with the hook.

Referring to the drawing the numeral 1 designates a hook body or stock, one side plate of which is removable. The hook is formed with a bill 3 and has a cavity 4 adjacent the bill and cavity 5 Communicat ing with the cavity 4 through a slot 5.

A safetylatch 6 ispivoted on the hook as at 7 and operates in the cavity 4. and across the entrance to the bill 3. The latch 6 is flat and'is snugly though shiftably fitted in between the side plates of the hook body. This latch 6 includes a hub 8 and a sector shaped latching portion or section-madeup v of radial bars 9 and a curved bar 10 all integral with each other.

The sector shaped portion blocks the entrance to the bill when the latch is in latching position. A. combined setting and stop finger 11 is integrally formed with thelatch and is adapted to be engaged by the rope, chain, eye or the like entering the hook to shift the latch to closed or latching position, the nngei 11 engaging the portion 12 of the hook to limit the movement of the latch to closed position. A stop lug 13 formed on the sector shaped latching portion engages the wall 14 of the cavity 4 to limit the latch in its opening movement I to a full open position wherein the entrance to the bill of the hook is unobstructed and the setting finger 11 ispositioned to be engaged by the object entering the hook.

Locking mechanism may be provided to hold the latch 6 iirthe latching position shown in Figures 1 and 2 and such locking mechanism is housed in'the cavity. 5 and has a bolt B operating through the slot 5 and engageable with a shoulder provided on the latch 6. The bolt may be projected by a spring S and manually retracted from an operating element 0 located eXteriorly of the hook. 7

In order to prevent the bolt from locking the latch in open position an extension 25 is formed on the {latch and obstructs the slot 5 when the latch is in open position. The bolt of. the locking mechanism snaps behind the shoulder 20 automatically when the latch is shifted to latching position.

I claim:

1. A safety hook comprising a hook body.

havin 'a bill and also havin a cavit ad'acent the bill, and a latch pivoted to the body and operating in the cavity and across the entrance to the bill, the latch having a portion adapted to obstruct the entranceto the bill in one position of the latch, means for limiting-the movement of the latch in one directionto open position, and a setting finger for automatically turning the latch to closed position, said hook body having an abutment portion engaging said setting finger for limiting the movement of the latch to full closed posit-ion.

2. lasafety hook comprising a hook body having a bill and also havlng a cavity adjacent the bill, and a latch pivoted to the body and operating in the cavity and across the entrance to the bill, the latch having a portion adapted to obstruct the entrance to the bill in one position of the latch, means for limiting the movement of the latch in one direction to open position, and a setting finger for automatically turning the latch to closed position, said setting finger limiting the movement of the latch to full closed position, said latch having a shoulder, and locking mechanism including a spring projected and manually retracted bolt engageable with the shoulder, the bolthaving an extension preventing the bolt from being projected to lock the latch in open position.
